Rustitution

Stock cables with a Rental 755 styled bar, I'm thinking I'm pinched some where So I'm going to take it apart again and try to reroute them again.

Also I should say I have the slack and everything i need it just won't snap back on it own

So i did this the other weekend and I'm just about finished but my throttle tube just doesn't snap back does anyone have any recomendations to resolve this, or has any ever run into this? please and thank you.
